ABSTRACT:
An acceleration device including an acceleration fuel spray nozzle arranged on the upstream side of the choke valve and a through aperture formed in the latter to allow the fuel spray from the nozzle to freely proceed to the engine even when the choke valve is closed. There is no unwanted squirt of fuel during engine starting or high speed operation and formation of any overrich fuel-air mixture or depletion of the fuel passage extending to the nozzle is effectively prevented.
